商品有机肥含有养分多但相对含量低,释放缓慢,而化肥单位养分含量高,成分少,释放快。两者合理配合施用,相互补充,有机质分解产生的有机酸和碳酸能促进土壤中难溶性磷酸盐、多种微量元素养分的转化,提高养分的有效性,提高肥料的利用率。卷心菜,学名结球甘蓝,又名洋白菜,包菜,为十字花科芸薹属蔬菜,是甘蓝的变种,含有丰富的蛋白质、脂肪等多种营养成分。近年来研究发现,其在预防动脉硬化、胆结石及癌症方面具有一定功效。由于受传统栽培模式与经验的影响,蔬菜作物的肥料投入量较大,不仅造成了养分失衡、产量提高受限及环境污染,也降低了蔬菜安全品质。本试 Commodity organic fertilizer contains more nutrients, but the relative content is low, slow release, and fertilizer unit nutrient content is high, less ingredients, release faster. The two are reasonably used in combination with each other to supplement each other. The organic acids and carbonates produced by the decomposition of organic matter can promote the transformation of insoluble phosphate and trace elements in soil, improve the availability of nutrients and increase the utilization rate of fertilizers. Cabbage, scientific name Cabbage, also known as cabbage, cabbage, Brassica oleracea vegetables, is a variety of cabbage, rich in protein, fat and other nutrients. In recent years, studies have found that it has some effect in preventing arteriosclerosis, gallstones and cancer. Due to the influence of traditional cultivation mode and experience, large amount of fertilizer is put into vegetable crops, which not only causes imbalance of nutrients, limited yield and environmental pollution, but also reduces vegetable safety quality.
